1.3.2. RECEIVERS ANTENNAS
For the operation of receivers, a telescopic (Fig.1, item 2) and mini-antenna (Fig.1, item 9) are
used.
It is recommended to use a telescopic antenna to receive signals in the range of 20 MHz ÷ 3
GHz. It is recommended to use a mini-antenna to receive signals in the range of 2 GHz ÷ 6 GHz.
Any of these antennas can be used to receive signals in the range of 2 GHz ÷ 3 GHz.
Antennas are connected to the ANT socket on the top panel of the main unit (Fig.3, item 5).
1.3.3. PARAMETRIC DETECTOR ST 100P
ST 100P is a transceiver device that detects the modulation of the reflected RF sounding signal
caused by low-frequency processes in working electronic devices.
The analysis of the detected signals is carried out on the basis of the acoustic information
heard in the headphones.
1.3.4. MINI-USB CABLE
The cable (Fig.1, item 6) is used to connect the main unit to the USB port of the PC.
1.3.5. PLAYER OF THE TEST SOUND (PTS). The player is not included in the Kit.
A player is required to search for eavesdropping devices. Any portable device equipped with a
speaker (smartphone, tablet, voice recorder) can be used. Purpose of the PTS:
creation of an acoustic signal (the correlation of this signal and the information obtained
using the ST 100 means that there is an active eavesdropping device with an unencrypted
transmission channel in the tested room);
forced inclusion of eavesdropping devices equipped with a VOX activation system;
localization of detected eavesdropping devices;
creation of the "masking noise" during the search operations.
MP3 files recorded on the USB flash drive. The user can use their own files (noise in the office,
people talking, music, etc.).
1.3.6. USB FLASH DRIVE
MP3 files (for PTS), this Manual and the ST 100 software recorded on the USB flash drive.
1.4. POWER SUPPLY
The device operates on a built-in battery, the charge level of which displayed using an
indicator in the information line (Fig.6, item 3). A fully charged battery provides 7 hours of
operation. The battery charged using a charger (Fig.1, item 5).
To do this, insert the charger plug into the socket on the side panel (Fig.3, item 12) and
connect the charger to the 220V/50Hz.
Charging is accompanied by a red or orange glow of the charger connection indicator (Fig.3,
item 11) on the side panel of the device. Full charging time is no more than 7 hours. When
charging is complete, the indicator will turn green.
It is allowed to use the device while charging the battery. In this case, the time required to
fully charge the device increases.

3.2.2. SETTING "0"FUNCTION
The function is intended to localize the signal source detected when using the SIGNAL
ANALYSIS AT A FIXED FREQUENCY function.
The use of this function is especially effective when searching for sources of strong signals,
when even with the minimum value of the gain the signal level indicator goes off scale and the
localization of the signal source is difficult. After turned on the function, the signal level at the
fixed frequency is zeroed and the difference level is displayed on the indicator.
To turn on the function, press the F1, the field of button will become lighter.
When using the SETTING "0" function, it is possible to:
change the bandwidth value (F2);
turn on OSCILLOSCOPE (F3);
change the gain value (F4).
To turn off the function, press the F1 again. The F1 button field will become darker.
3.2.3. OSCILLOSCOPE FUNCTION
The OSCILLOSCOPE function is available when using:
SIGNAL ANALYSIS AT A FIXED FREQUENCY function

3.2.4. SEARCH FOR VIDEO CAMERA SIGNALS FUNCTION
When moving the marker, the parameters of each detected signal are analyzed for their
correspondence to the parameters of the signals from video cameras. If the comparison is
positive, the video camera detection indicator appears in the information line (Fig.6, item 2).
3.3. LOCALIZATION MODE
The mode is intended for localization of radio signal sources in the tested room. Moving around
the room, the user observes the change in the levels of several of the most powerful signals.
In the mode, an adaptive change in the receiver gain is implemented. This increases the
reliability of localizing the signal source.
The device monitors the increase, decrease and maximum values of signal levels relative to
the levels obtained when the mode was turned on. This makes it possible to determine the
position of the user relative to the signal source.
The mode allows you to distinguish external signals from signals, sources of which are located
in the tested room.
Turning on the LOCALIZATION mode is possible from the PANORAMA mode or DIFFERENTIAL
mode by pressing F1. The screen view is shown in Fig.17.

3.4. AUTOMATED MODE
AUTOMATED mode detects signals whose amplitude exceeds the adaptive detection threshold.
The mode is turn on from DIFFERENTIAL mode or PANORAMA mode by pressing F2 button. The
search for signals is performed within the established range, taking into account the results
obtained in the DIFFERENTIAL mode (if the AUTOMATED mode was switched on from the
DIFFERENTIAL mode). All detected signals are assigned one of three attributes.
The default is:
"NON-DANGEROUS" - signals from base stations of mobile communication systems;
"DANGEROUS" - signals of wireless mobile devices;
"UNKNOWN" - all other signals.
The ST 100 software allows you to assign a "DANGEROUS" or "NON-DANGEROUS" attribute to
certain frequency bands.
